The Joker is back already (4th episode presented on DVD), and that's fine with me: he's always extremely entertaining. This time, he has green laughing gas as his weapon. He piles it like toxic waste on top of a barge that sails down the city's waterway and everyone who gets whiffs of the stuff gets the giggles. Unfortunately, it's not funny for the citizens of Gotham because why they are uncontrollably laughing, The Joker and his henchmen are stealing them blind. At one point, The Joker jokes, "This is what a call a sidewalk sale" as he mugs people of their money and jewelry walking down the street.
Also unfortunate is the news bulletin that this gas leave people brain-dead if they are exposed to it for too long. That dilemma hits home quick when Batman's butler Alfred is affected. Batman quickly dons a gas mask while Alfred is destroying his house and laughing at the same time.
How will Batman counter this strange attack from the Joker, especially after "Captain Clown" spins him around and dumps into a garbage can and throws him into the river?
There are lots of jokes (mainly puns), colorful graphics and wonderfully entertaining characters in this episode. I am beginning to fully see why people rave about this animated series.
